Tool mounting device for turning center

Abstract

Provided is a tool mounting device for a turning center that allows a rotating tool (1A) to be clamped / fixed using a shared clamp mechanism ( 8 ), and a turning tool ( 1 B) to be clamped / fixed in an engaged / locked state in a turning center. In the turning center configured with the shared clamp mechanism ( 8 ), a cylinder device ( 9 ) acting as a drawbar drive device ( 9 ) of the clamp mechanism ( 8 ) has a first clamp position (b) and second clamp position (c) in relation to a release position (a); a rotation allowance gap ( 14 ) is maintained between the stopper ( 12 ) and the bearing unit ( 13 ) in the first clamp position (b) to specifically clamp / fix the rotating tool ( 1A); the reciprocating driver ( 11 ) is driven by an amount equal to the rotation allowance gap ( 14 ) in the second clamp position (c); and when the bearing unit ( 13 ) and the stopper ( 12 ) are brought into contact and a load is imposed, the stopper ( 12 ) is supported / stopped by the bearing unit ( 13 ), and the reciprocating driver ( 11 ) is engaged / locked by the wedge mechanism ( 18 ) in the position of the return blocking state in which the return of the drawbar ( 7 ) is blocked.

Description

technical field [0001] The present invention relates to a tool installation device of a turning machining center, which can properly replace a rotating tool and a turning tool for milling and cutting (turning). Background technique [0002] In the turning machining center, the main shaft is provided rotatably with respect to the ram through the bearing part, and the main shaft is provided with a mounting engaging part for engaging with a tapered shank provided at the base end of the tool. (taper shank), and a clamping mechanism is provided on the main shaft, which clamps the clamping protrusion of the taper shank by pulling the draw bar, and the taper shank Draw it closer and engage it on the installation engaging part, so that any tool can be detachably installed and fixed on the main shaft. In addition, the clamping mechanism is set to perform clamping, The release action allows each tool to be properly loaded and unloaded through this common clamping mechanism. In the ca...

Problems solved by technology

[0004] Therefore, since a hydraulic cylinder device is required, no hydraulics can be realized, and energy saving and resource saving cannot be realized

[0005] On the other hand, for example, simply implementing the wedge mechanism (Japanese Patent Laid-Open No. 2004-202659 ) developed by the applicant, which can resist a large cutting force even if an air cylinder device is used, etc., in a turning center, it is necessary to be able to Rotationally clamping and fixing, since it is necessary to constitute a common clamping mechanism for clamping and fixing the rotating tool and the turning tool, it is relatively difficult for the turning machining center
